All designs are marred by uncertainties and tolerances in dimen- sions, load levels etc. Traditionally, one has often over-dimensioned to take these uncertainties into account. The demand for optimized designs with high quality and reliability increases, which means that more sophisticated methods have been developed, see e.g. Lochner and Matar (1990). By describing the fluctuations in design para
Abstract What are the pedagogical impacts of internationalisation on the development of higher education in Europe? How can we proceed in this process and take a pedagogical stance on the issue? This theoretical paper is partly based on a series of empirical studies conducted by the author, investigating students’ and teachers’ experiences and understanding of an internationalised educational cont
Understanding spatial and temporal variability in the distribution of seabirds is fundamental for the conservation and management of marine ecosystems. In the absence of large-scale systematic survey data, the application of standard habitat modelling techniques to predict the at-sea distributions of seabirds at large spatial scales has been limited. In this study, we examine the utility of relati
Abstract in Undetermined This article examines the rise of monasticism in Late Antiquity. It reveals the close link between traditional Greek society and culture and the rise of monasticism, based on historical evidence and the literary character of the early monastic texts. While not denying the innovative character of much of early monastic life, the rich variety of forms of monasticism, and the
Popular Abstract in Swedish Infektioner i urinvägar, tarm och luftvägar orsakas av bakterier som speciellt anpassats till respektive vävnad. Infektionen börjar med att bakterien binder till slemhinneytan, och därmed sätter igång inflammation och försvar. Urinvägsinfektioner (UVI) är en värdefull modell för att förstå de molekylära detaljerna som avgör balansen mellan värd och bakterie. UVI orsakaBacterial adhesion to the bladder mucosa is a critical step for the establishment of Escherichia coli bacteriuria. The P-fimbriae, encoded by the pap gene cluster, are considered as virulence factors but the mechanisms have been debated. This study defined the roles for P fimbriation during the early colonization of the human urinary tract. Patients with recurrent UTI were first subjected to deli
In the light of technological changes, changes in business contexts, decreased number of IS students, changes in educational systems, etc., IS education commentators have urged the IS community to develop new and alternative IS curricula. In response to this, we present a model curriculum for a Bachelor of Science program in business information systems design (BISD 2007). The curriculum has a str
Popular Abstract in Swedish För många cancerpatienter är strålbehandling ett viktigt behandlingsalternativ. En framgångsrik behandling kräver att den absorberade dosen till patienten kan ges med stor noggrannhet. Detta eftersom en liten avvikelse i absorberad dos kan påverka behandlingens resultat. Strålbehandling sker idag med avancerad teknik och utrustning där osäkerheterna i varje led i behandThis thesis presents a new verification concept, the virtual accelerator, for dose calculation algorithms used in treatment planning systems (TPSs) for external beam radiotherapy. The algorithm input data required to implement a treatment unit in the TPS are generated by Monte Carlo simulations as are the beam reference data needed for the subsequent evaluation of the dose calculation algorithm. T
Popular Abstract in Swedish Blodåderförkalkning och dess komplikationer såsom hjärn- och hjärtinfarkt är bland de vanligaste orsakerna till sjukdom och död i vårt samhälle. Flera faktorer är av betydelse för uppkomsten av åderförkalkning. I denna avhandling presenteras studier av substanser frisatta från kärlendothelet (blodkärlväggarnas insida) respektive från vita blodkroppar, och dessa substansThis study was undertaken to evaluate relationships between endothelial function (assessed as mediators of endothelium-derived vasoactive factors such as nitric oxide [NO], prostacyclin [PGI2] and endothelin [ET-1] ), and risk factors for atherosclerosis, as well as to study possible relationships between endothelial function and leukocyte activation (indicated by measurements of leukocyte-derived
The overall aim of the chapter is to reflect a classroom project on creative learning processes by four “dialogues” between researcher and teacher perspectives on a sequence of themes that lead up to the morale of the tale; Computers and learning, Creativity and education, Creative teaching and Creative learning.
Clusters, nanoparticles, nanowires, long molecules as nanotubes and polynucleotides, and functional supramolecular nanostructures are currently considered as potential building blocks for nanotechnology and nanoelectronic devices and circuits, and development and introduction of new methods to control effectively their structure, composition and nanoscale organization are necessary. Here we descri
This thesis concerns the analysis of anthropogenic substances of the compound class known as persistent organic pollutants (POPs). Sample preparation perspectives for the analysis of POPs in the environmental matrices water, soils and sediments are presented. This thesis features reasonably cheap and uncomplicated methodology capable of fast screening of POPs. It displays how quantitative extract
The complex interplay by tunneling and scattering in quantum cascade lasers is analyzed with nonequilibrium Green's functions. Data for a recently proposed simple structure based on only two wells per period is presented. This simple structure allows to visualize the relevance of the tunneling resonance very clearly. It is argued that a QCL design needs at least three levels per period, thus furth
